HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 396,435, dated January 22, 1889.

Application filed June 1, 1888. Serial No. 275,702. (No model.)

To all whom it may concern:

Be it known that I, JAMEs l'). SnoAN, of Rushville, in the county of ltush and State oi? Indiana, have invented a new and Improved Hose-Coupling, of which the. following is a full, clear, and exact description.

The object of my invel'ition to produce. a hose-coupling simple in eonsiruction' and effective in. operation; and it consists in the parts which will be hereinafter described, and pointed out in the claims. I

Reference is to be had to the acctnnpanying drawings, forn'iing a part of this specification, in which similar letters o1- reliere nce iinlientc correspoi'nling parts in all the gnres.

Figure 1 i.'e n.'esents a side view oi my coupling engaging two pieces oi. hose. Fig. 2 is a central longitud in al sectional view 0 if tl I c parts shown in Fig. 1. lfiig. is a cross-section on the line 51:11: of Fig. l. l ig.-'l is a side view of the main body of the coupling with the hinge removed. Fig. 5 is an inside view of the hinge and its two springs. Fig. i; is a side view of a coupling, partly broken away. Fig. 7 is a longitlulinal sect ional view 01' a nozzle connected to a hose by means of my coupling, and Fig. S is a erossseetion on the line y 1 of Fig. 7.

A B represent two pieces of hose connected by means of the improved coupling- I C is a short pipe provided on one end with a collar, C, and also provided with a middle. collar, 0

C indicates scrmv-threads on the outer side of the pipe adjoining the collar and C are external corrugations extendin g from the screw-threads aforesaid to the end of the pipe.

D D indicate two collars, each provided with internal. scrmv-threads, ((1.7, and external pins, (1' d.

The body of the coupling is iiulicatiwl. by E. Said body is DI'OYltltHi on its outer side with an end collar, E, a middle collar, E 1", screwthreads E, adjoining said collar, and external corrugations, A part of. the side at one end of this body is cut away "or provided With a large opening, as shown in Fig. i, and indicated by L O. The part B of the middle opening L O aforesaid.

vided with a transvin'se opening, E (seedotted lines, Fig. 4,) for the reception of a hii'igerod. The high is provided with a smaller log or stop, E.

The body of the coupling 11. is provided with a recess or depression, lfi. (Seelrigs. .l. and 3.) Said bod y is also proviijled on the inner side, under the lug E, with a recess, E, For the reception of a Hat spring, to be hereinatter specified. The outer edge of the opening L O is beveled at E and the inner side of the body E is provided with a groove, E

1* represents a hinge for closing the opening ll 0. The respective outer sides of the hinge are provided with tlal'iges l!" F Adjoining the flange 11 is an outer extension, F The under side of the extension l is recessed or grooved lengtlnvise.

h I iiulieate two lugs on the hinge. Each lug 11" is provided with a transverse opening, f. (Shown in dotted lines, Fig. 5.)

F is a flat s n'ing having one end enga ed to the inner side oi the hinge between the lugs h. The ol'iteri-nul of this spring extends outward between the two lugs I! aforesaid.

F is a yoke spring or catch engaged to one end of the hinge between the outer flanges, 1 F aforesaid.

F' is a short rod or pin, Fig. 3, for engaging the hinge to the body of the coupling. Said pin engages the transverse openings in the lugs 1 and E. The respective sides of the hinge are provided vith beveled F F G indicates anozzle. The inner end of this nozzle is provided with two flanges, G G and an intervening body, G, said flanges and body practically correspomlii'ig in construction to the parts of the companion coupling piece 0' 0*, as shownin Fig. :3.

G represents the main body of the nozzle. The outer end of this nozzle is provided with internal SGIOW-tll'lfit'ttlS, g.

It is a short pipe provided with external screw-threads, 7t, and a shoulder, ll. The diameter of the opening in. the pipe H is uniform throughout its length. The opening in the main body of the nozzle is slightly tapering from the flange G to the outer end. The pipe II is ei'igaged to the nozzle by means of the respective threads of said parts. There are a series of wings or lugs, G on the inner side of the nozzle and midway thereof for breaking a stream of water.

1 represents a short pipe, provided on one end with a slnnilder, l, and also provided on. its other end with a larger shoulder, P. The. shoulder I is provided with internal screwthreads, I, for engaging the pipe to a plug and discharge-pipe at the engine. This pipe, like the inner end of the nozzle and theparis (I U (.1 is constructed so as to engage with the body and hinged part of the coupling.

.1 indicates a mcking-ring for forming a water-tight joint between the connected ends of the coupling.

The operation is as follows: The collars .D D are engaged on the respective ends of the hose. Each hose is then engaged to the corrugated ends C E, respectively, of the coupling. The collars are then turned so as to engage their threads with the threads (1" E, each collar being screwed on so as to lie in contact with the collars PIKE, and respectively. It will be observed that each collar 1) D is shorter than the corrugated ends of the coupling. This permits the outerend of each corrugated part to expand on the inside of the hose and cause said hose to expand over the outer edge of each collar l) l). This i'feati'n'e, with the corrugations, forms a strong connection between the hose and (-on ]ing.

The normal. condition of the parts when the hinge is closed and the device coupled is shown in full. lines, liig. The dotted lines in said. (i we represent the position oi? the parts when the hinge is open. When the hinge is closed, the yoke-spring lfi engages the lug E and locks the parts. By prying into the recess E under the yoke-spring alj'oresaid said spring may be disengaged from the lug E When so disengaged, the fiat spring 13" will be exerted to open the hinge. The extent to which the. hinge may be opened is limited by the small lug It" on the lug E The yokespring has an inward tendency. Said spring is therelbre caused to engage the small lug E" when the hinge is open, as shown in dotted lines in Fig. I

\Vhen the hinge is open, a part cmrresponding with the construction shown by (i (1" (1 (such as is also shown on the nozzle and plugpipe I) may be engaged within the body or hinged part of the coupling. Then by closing the hinge and causing the yoke-s 'n-ing F to engage with the lug E"- the several parts oi. the coupling are firmly united.

The locking between the two main parts of the coupling is eli'eeted by causing the collar U of the part 0 to engage and lock with the beveledge of the hinge, and also lock with the groove in the inner side of the body E.

The lugs d. are for turning the collars D D, so as t-o'engage the internal threads of said collars with the external threads adjoining the corrugated parts of the coupling.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a hose-couplin g, the combination, with. the coupling-body E, provided with a lug, E and a projection, E", a hinged portion, F, provided with a tomvardly extending springcatch adapted to engage the lug 1% when closed and the projection E" when opened, said hinged portion. and the body portion provided with internal grooves, of a pipe provided with an external. eollaradapted to enter the internal grooves in the coupling, substantially as and for the purpose specified.

2. A hose-coupling consisting of a body provided with a lv E said lug being provided with a smaller lug, E, a hinge engaged to said body, said hinge portion being provid ed with a spring-catch, F, the inner sides of the body aforesaid being grooved, in eo1nbination with a pipe provided with a collar adapted to engage with the groove in the body aforesaid, substantially as and for the purposd specified;
